~ low powered nvr and doesn't offer 5ghz

~ normal wifi antennas

~ the ddwrt router

1 hour later after wifi scan:

21 wifi devices in just this small area

Back in El Dorado where my grandmaw owned 6 acres of land....the most detected would be 3-6.

The usage of wifi has risen at an alarming rate. In my days....you'd see this in the city but not in the county.

[security-tips]

ok once upon a time maybe but it is visible.

Note the hidden SSID part....and think about them being clients not servers such a router acting as a wifi server that you'd connect into.

yeah but...

I got the nvr's mac address.....ok...follow this through....then what? Are you a security camera add on to my network that didn't have the mach code process ran on? Do you understand there is no wifi pc connecting into the nvr. IT DOES NOT ALLOW IT. ONLY CAMERAS..

The nvr would have to be plugged into the router and you'd have to be on the router's wireless network.

No wait....what if you were a camera with a vpn connection to the internet trying to spoof and run an ip tunnel while modifying my firmware if I'm an NVR? or nothing.....no matter how techy you try to make anything sound...

Outside of a high tech denial of service attack while spoofing the nvr's mac.....a problem exist with this though....if you were irradiating the nvr to keep it from communicating while *aiming* a faked mac address to fool the cams into believing you were the nvr......

OK follow this through.....say I have jamming equipment....I put it in front of the nvr to block out it's signals....now I place another modified nvr same type but a spoofed mac on top of the jamming equipment in order to fool the cameras.....

🤬

🥴

I would have never thought of you putting an isolinear rod in your rectum with an active wifi repeater AP bridge....

The cams try to connect to the NVR as clients....with no webpage for the end user to connect to the cams. Does that make sense? Think opposite.

Server -> Cams Cams -> Server

OK understand the match code process....when the hm241 is paired to the cam....you plug ethernet into the back of the hm241 then into the back of the camera. Now both have each other's mac address. This means they can only allow *matched code* or specific MAC ADDRESSES.

Even if you could fake as if you were a camera....what could you do? Unless you've hard wired connected into the NVR though you can't...but ok lets follow this out...what could you do? You'd be limited in protocols or methods of communications to the NVR.

As a cam ...you can't tell the NVR to reboot. IT CAN TELL YOU TO REBOOT.

In my case as an added safety precaution, I use the factory setting that it shipped with. It's using a foreign grade of wifi. I don't live near any airports or other locations that it would cause interference. The bands being used are hidden to normal american wifi such as on cellular, tablets, laptops etc. It operates at higher bands and by doing so doesn't deal with wifi interference where a neighbor is using the same wifi channel.

So for you to access them OR even see them...you'd have to be using a router's sniffing or wifi ssid scanning....or some kind of imported wifi card that was set to use foreign wifi.

OK Do you understand you are trying to hack into a wifi client?

Client: If I have a password I can connect to you NVR or mr router.

Server: You better have the correct MAC and password!! Otherwise I won't let you connect.

Client: 🥴 I'm only a wifi client. Why does this douchebag keep trying to connect to me??

[security-tips]

Let me know when you're done hacking my security cams based on all your little play by plays and tech tip offs from german intel.

What's that strange pins on my board that says 3v3 TX RX GND?

It's for diagnostics and upgrading firmware.

[security-tips]

Take note of the IP Address range 172.20.14.xxx. How do I get my cam working with an nvr like this you ask? Uhhh! but it says ONVIF but I connect my camera and it don't work!!!

Step 1: Use a spare router and sit to the side when done. Set the router's DHCP addressing so that any device that gets assigned an IP falls within 172.20.14.2 - 172.20.14.255.

Plug the camera into the router and config your username and password. When done remove and connect the cam via wifi manually into the hm241.

Unless you understand networking or you're a certified Network technician, you won't realize just how much they are trying to force you to use proprietary cameras. By not allowing the sub-range 172.xxx to be modified, it would take knowledge to add non company brand cams. Most IP cams out of the box default to 192.168. xxx . xxx IP Address ranges. When you plug it into the nvr, it can't communicate.

For added security in case any can or is viewing your tv / monitor....use a long enough password that anyone being told the password would have to go out of their way to write it down.

Agent DVR....8 cameras all at minimum 5mp cams....test ran for entire day without powering down on an i5 3400ghz with 32 GB ram....not one problem. (side by side with CodeProject AI Server on the same pc)

[security-tips]

For just a general alarm....sounds just like a siren but not as loud....it does have the built in capability....you can simply press mute on your tv remove.

Personally, I opened the alarm.wav file and extended the length of the alarm to 1 minute.

Every one of those in that list to the right...triggered an alarm while muted.

If you want an upscaled more secure version of that use your pc's audio out jack to something that has a push button to mute the speakers.

Ok so I have home assistant os setup now how the heck do I integrate my siren etc into this!!!??

[security-tips]

Current;y have 2 x 3B models and 2 x 4B models.

Utilizing Amcrest AI cams....hint the AI part....they have it already built in....before you dev into CodeProject AI....

So for an existing Amcrest AI cam....with IVS rules...

= AI + AI

It's adding a filter after Amcrest AI determines the object is a person or vehicle....then IF CodeProject AI Object Recognition determines it is....then it triggers the Alert....

Because the Amcrest Cams have integrated AI....this lowers the usage of CodeProject AI Server.....it only runs object recognition on the output of an IVS perimeter breach.....now keep in mind the Amcrest cams themselves have NO LIMITATIONS on their FPS....they have built in AI with IVS.....so setting agent DVR to use a low fraame rate at high resolution....and skip to motion can make an i5 with 32 GB RAM....A SUPER BEAST KILLING MACHINE IN A LAND OF DWARFS!!!

[security-tips]

I don't recommend anything less than an i5 with 32 GB ram.
